I use it with woodworking trimmer. Compared with router bit, finish of plate end face, tenon cut, groove cut and so on, the cut section is sharp and smooth finish can be satisfied. Two blades of long blades and four blades distinguishably from the plate end finish and the deep mortise, the two blades of short blades are distinguished by shallow tenon and groove cutting. I think that it does not change to the finished state with 2 blades, 4 blades.

I bought it as a router bit with a hobby woodworker. It is satisfied with the smoothness of the machined surface, that the noise during machining is small. I felt that kickback was also unlikely to occur.
